Description

Technical Field

[0001] The utility model belongs to the field of two-wheeled electric vehicle awnings, and in particular relates to an electric vehicle awning window opening device. Background Art

[0002] Existing electric vehicle awnings generally have windows on the front windshield, but most of the window opening devices have problems such as limited adjustment angles and unstable opening and closing. Patent 202121548231.8 discloses a front windshield window pushing device, which has the following disadvantages in actual use: 1. The horizontal through hole extends downward to form an adjustment slit, which occupies a large area of ​​the window transparent plate and blocks the line of sight; 2. When the screw is turned to loosen the horizontal through hole to expand the inner diameter, the teeth on the inner side of the horizontal through hole are elliptical and leave the teeth on the horizontal connecting rod, but in this process, the teeth on the opposite side of the horizontal adjustment slit opening are aligned with the horizontal The teeth on the connecting rod always have meshing parts, which leads to a large number of turns of the screw when adjusting the window opening, a large opening distance of the lateral adjustment gap, and the meshing teeth can never be completely separated. Therefore, there is a large resistance when adjusting the window opening, and the window bracket can only be rotated by forcibly jumping the teeth; third, the tensioning parts are bolts and nuts. The process of tightening or loosening the lateral connecting rod by turning the bolts for multiple turns is time-consuming and laborious. In the semi-loose state without tightening the bolts, the window cover will vibrate as the electric vehicle travels, which will produce noise and may accidentally close in the open state, which is unstable. Summary of the invention

[0022] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0023] like Figure 1 As shown, an electric vehicle awning window opening device includes a front windshield support and a window support, a screw 4 passes through a clutch wrench 1 and a fixing member 2 horizontally, and the tail end is connected to a movable member 3, the first end of the fixing member 2 is provided with two or more rotationally symmetrical fan-shaped inclined surfaces A201 that match the fan-shaped inclined surface B101 provided on the inner side of the clutch wrench 1, and the second end of the fixing member 2 is provided with a first positioning tooth 202 that meshes with a second positioning tooth 301 provided on the outer end surface of the movable member 3. In actual use, by rotating the clutch wrench 1, the fan-shaped inclined surface B101 slides radially relative to the fan-shaped inclined surface A201 to generate an axial displacement, so that the first positioning tooth 202 of the fixing member 2 and the second positioning tooth 301 of the movable member 3 are closely meshed to completely separated within a limited axial displacement, that is, by rotating the clutch wrench 1, the movable member 3 is locked or released, and the opening angle of the window can be fixed in the state of locking the movable member 3, and the opening angle of the window can be adjusted by rotating the movable member 3 in the state of releasing the movable member 3, and the operation is simple, convenient and fast.

[0024] like Figure 1 —4, a positioning rod 102 is axially arranged on the outer circle of the head of the clutch wrench 1 to slide along the outer surface of the fixing member 2, and a first step 203 and a second step 204 are arranged on the outer surface of the fixing member 2 to limit and lock the sliding range of the positioning rod 102, so that the clutch wrench 1 can rotate within a limited range and cannot rotate continuously beyond the steps, so that the axial displacement generated by the radial sliding of the fan-shaped slope B101 relative to the fan-shaped slope A201 is accurate, and when the clutch wrench 1 rotates from the first step 203 to the second step 204, the first positioning tooth 202 and the second positioning tooth 301 are changed from tightly engaged to completely separated. During specific implementation, the clutch wrench 1 is rotated to make the positioning rod 102 slide to the first step 203, and the fan-shaped slope B101 radially slides relative to the fan-shaped slope A201 to generate axial displacement so that the first positioning tooth 202 is tightly engaged with the second positioning tooth 301. At this time, the movable part 3 is in a locked state, and the window opening angle is fixed; conversely, when the clutch wrench 1 is rotated in the opposite direction to make the positioning rod 102 slide to the second step 204, the fan-shaped slope B101 radially slides relative to the fan-shaped slope A201 to generate axial displacement so that the first positioning tooth 202 is separated from the second positioning tooth 301. At this time, the movable part 3 is in a loosened state, and the window opening angle can be easily adjusted.

[0025] like Figure 2As shown in FIG. 4 , the inner side surface of the positioning rod 102 is provided with an axial groove 103, and the front of the first step 203 is provided with a protrusion 205 corresponding to the groove 103. The groove 103 and the protrusion 205 are arranged to cooperate and lock, which can make the locking state of the clutch wrench 1 more stable and prevent it from rotating in the circumferential direction due to the vibration of the electric vehicle, making the window fixation unreliable.

[0026] like Figure 1 , 5 As shown, the screw 4 is a self-tapping screw, and its tail is tightly connected with the movable part 3. In specific implementation, the screw 4 sequentially passes through the clutch wrench 1 and the fixing part 2 horizontally and a certain clearance is set between the clutch wrench 1 and the fixing part 2. The tail end is fixedly connected to the movable part 3. The screw 4 is set as a self-tapping screw, which makes the assembly of the window opening device simpler, reduces the process and accessories, and saves costs. Figure 6 As shown, or a lock nut 401 is provided at the tail of the screw 4 to limit and lock the movable part 3, and a notch 302 is provided on the lateral part of the movable part 3 to accommodate the lock nut 401, and the height of the notch 302 is greater than the height of the lock nut 401, so that during installation, a wrench can be inserted into the notch 302 to clamp the lock nut 401 to adjust the locking distance of the clutch wrench 1, so that when the clutch wrench 1 is rotated to the first step 203, the lock nut 401 just limits and locks the movable part 3, and the setting of the lock nut 401 can ensure that it will not rotate relative to the screw 4 to change the locking distance, and prevent the clutch wrench 1 from losing its function when the locking distance is too large, thereby extending the service life and durability of the device.

[0027] like Figure 1 , 5 As shown, a compression spring 5 is axially arranged between the fixed part 2 and the movable part 3, and the compression spring 5 is sleeved outside the screw 4, with one end of the compression spring 5 abutting against the fixed part 2 and the other end abutting against the movable part 3. In specific implementation, the compression deformation of the compression spring 5 is greater than the maximum axial displacement caused by the radial sliding of the fan-shaped inclined surface B101 relative to the fan-shaped inclined surface A201. When the clutch wrench 1 is rotated to lock the movable part 3, the compression spring 5 is in a compressed state; when the clutch wrench 1 is rotated in the opposite direction to loosen the movable part 3, the compression spring 5 will release the elastic force to push the fixed part 2 and the movable part 3 to separate automatically. The arrangement of the compression spring 5 to assist in pushing the fixed part 2 and the movable part 3 apart can make the first positioning tooth 202 and the second positioning tooth 301 separate more quickly and cleanly, thereby easily pushing the movable part 3 to rotate radially, making it simpler and more convenient to adjust the window opening degree.

[0028] like Figure 7As shown, the window bracket is composed of a U-shaped bracket 6 and a top crossbar 601, the transverse part of the movable part 3 is connected to the top crossbar 601, and the longitudinal part is connected to the upper end of the U-shaped bracket 6, or the movable part 3 and the window bracket are set to be an integrally formed frame structure. The U-shaped bracket 6 in this embodiment is only used as a preferred structure and is not limited to this shape in actual application. The advantage of connecting the movable part 3 with the window bracket separately is that the window bracket can be made of metal pipe fittings, which has high strength, stable structure and is not easy to deform; while the movable part 3 and the window bracket are made of integral plastic casting, which has the advantages of fast production speed and low cost, no need for other connection and locking processes, and simple operation. A window transparent plate 602 is fixedly installed on the window bracket, and the area of ​​the window transparent plate 602 is designed to be larger than the frame area of ​​the window bracket to prevent rainwater from entering the car and wetting the driver.

[0029] like Figure 7 As shown, the above-mentioned electric vehicle awning window opening device, the lower end of the fixing member 2 is fixedly connected to the front baffle bracket, the transparent baffle is fixedly installed on the front baffle bracket, the upper part of the transparent baffle is provided with a window, the front baffle bracket is composed of two vertical rods 206 and a bottom cross bar 207 to form a U-shaped structure, the vertical rod 206 is a hollow structure, it can be understood that the upper part of the vertical rod 206 of the U-shaped structure has a very long force arm relative to the lower part, and it is easy to swing left and right for a certain distance under the action of external force, and the lower end of the fixing member 2 is sleeved on the upper part of the vertical rod 206 and is locked and fixed by screws. In actual operation, when the clutch wrench 1 is rotated to lock the movable member 3, the fixing member 2 will drive the upper part of the vertical rod 206 to swing inward for a certain distance, and the window opening angle is fixed at this time; when the clutch wrench 1 is rotated in the opposite direction to loosen the movable member 3, the meshing state of the first positioning tooth 202 and the second positioning tooth 301 is released, and the window bracket can be easily pushed to make the fixing member 2 and the vertical rod 206 swing outward for a certain distance, and the window angle can be adjusted.

[0030] like Figure 1 As shown, the tooth surfaces of the first positioning tooth 202 and the second positioning tooth 301 are inclined surfaces or arc surfaces. When the clutch wrench 1 is rotated to loosen the movable part 3, the inclined surface principle of the tooth surface can be used to easily push the movable part 3 to separate the first positioning tooth 202 from the second positioning tooth 301, thereby adjusting the window angle.

[0031] like Figure 7 As shown, the electric vehicle awning using the window opening device includes two electric vehicle awning window opening devices that are symmetrically arranged on the top of the window bracket. Their structures and functions are symmetrical and consistent, and are not described in detail here.
